Title: Improvements in or relating to densitometers
IPC: G01N21/59
Filed: 1960-03-22
Abstract: 970, 351. Photo-electric densiometers. JOYCE, LOEBL & CO. Ltd., KINGS COLLEGE UNIVERSITY OF LONDON, and E. M. DEELEY. June 21, 1961 [March 22, 1960], No. 10134/60. Heading G1A. An integrated absorption coefficient for an object having non-uniform absorption characteristics is determined by scanning the object with a flying spot scanner and integrating the logarithm of the instantaneous attenuation. A test object 2 Fig. 2 consisting of a stained specimen or a photograph is scanned by a television-type raster on a cathode-ray tube 1. Light transmitted falls on a photomultiplier, connected in a feed back arrangement which makes the anode voltage depend upon the logarithm of light intensity falling on the cathode, This voltage is integrated over a scan by integrator 12 and displayed on a meter 16 or record upon a signal from a push button 17. Sweep circuits 14, 15 control a gate 13 so that integration takes place only when a desired part of the object is scanned. Alternatively the desired part may be surrounded by a dense mask, gate 13 being closed when the input falls below a predetermined level. The light beam may be bent through a right angle, Fig. 1, and a light source 6 is provided so that an image of object 2 may be initially focused on the screen of tube 1, to ensure that the scanning spot will be focused on the object. To reduce the effect of stray light, the spot may be intensity modulated with a 1-2 kc/s square wave, but in this 'case the negative feedback arrangement is replaced by a logarithmic function generator.

Abstract: 954,456. Scouring pads. COLGATEPALMOLIVE Ltd. March 15, 1963 [March 16, 1962], No. 10162/62. Heading A4R. [Also in Division B3] A method of making steel wool pads comprises feeding a substantially continuous strip or a number of superposed substantially continuous strips of steel wool between a pair of pressing rolls at least one of which has circumferentially spaced recesses in its surface to produce spaced compressed regions transversely across the strip or strips. A continuous cylindrical wound strip 1 of steel wool is formed by diagonally feeding a web 2 of steel wool, through a soap or synthetic detergent impregnation unit 5, on to a hollow rotating mandrel 3. A web 10 of steel wool, paper or fabric from a bonding, rust-resisting, pH adjusting and/or detergent impregnation unit 11 and dryer 12 is fed through the mandrel 3 to form a core. The strip 1 is drawn between driven rolls 20, which compress the longitudinal edges 30 and then between pocketed driven rolls 25 which compress spaced transverse portions 31 of the strip 1 as well as the edges 30. Inserts 40 on the upper roll 25 have serrated edges which form partial severings across the portions 31, while one insert 40a has a knife edge which severs the strip once every revolution of the rollers 25. The severed ribbons of pads pass on to a belt conveyer 80 and through a drying or cooling tunnel 81 to a packing station where they may be packed concertina fashion in cartons. The impregnation bath 5 may contain a soap made from Palm Oil fatty acids and Palm Kernel/Coconut Oil fatty acids using an alkali mixture of potassium hydroxide and sodium hydroxide in the ratio 8 to 1. The web 10 may comprise a cotton bandage and the bath 11 may contain a sodium silicate solution. The web 2 may be sprayed with a solution having 1 per cent. sodium dodecylbenzene sulphonate and 1 per cent. sodium silicate. In another embodiment, Fig. 7, the web is formed from two continuous strips of steel wool 100, 101, sprayed with soap or synthetic detergent from nozzles 116, 117, and a strip 102 or textile or paper passed through an adhesive applying bath 115. Other numbers of strips some or all of steel wool may be used. The centre strip may be a cotton bandage and be impregnated with sodium dodecylbenzene sulphonate and sodium silicate. The central strip may be replaced by two strips of steel wool impregnated with a heavy duty detergent. The central strip may be thick absorbent paper or a thin coated paper impregnated with sodium silicate.

Patent GB-711657-A (GB)
Title: Improvements in or relating to the production of glycerine
IPC: C11D19/00
Filed: 1952-04-24
Abstract: Glycerin is obtained by the hydrolysis of chlorohydrins in which an aqueous solution of dichlorohydrin isomers, obtainable by reacting allyl chloride with chlorine in an aqueous reaction medium, is treated with an alkaline compound to convert the isomers to epichlorhydrin which is blended with a further quantity of the aqueous solution, the chlorohydrin present in the resulting mixture being hydrolysed in known manner to glycerin. The dichlorohydrin isomers are converted to epichlorhydrin, preferably by heating the solution in the presence of the alkaline compound, e.g. caustic alkali or lime, which is preferably present in an excess of about 2 to 20 per cent weight of the theoretical amount.  The dichlorhydrins may be converted to epichlorhydrin by passing the dichlorhydrin solution, heated to 65-100 DEG  C., into the upper portion of a stripper unit together with the required amount of caustic alkali or other alkaline substance.  Steam is passed up through the stripper and the epichlorhydrin distils off with the steam.  The distillate condenses as an aqueous solution containing epichlorhydrin.  The epichlorhydrin/dichlorohydrin mixture is hydrolysed to glycerin at elevated temperatures.  In the example, allyl chloride and chlorine are reacted in aqueous medium to produce a solution containing dichlorohydrin isomers which is neutralized with caustic alkali; part of the solution is treated in a stripper unit at a temperature of about 93 DEG  C. with 4 per cent aqueous caustic alkali; steam is introduced near the bottom of the stripper column and the effluent containing epichlorohydrin is combined with the rest of the solution containing dichlorohydrin polymers; the resulting mixture is hydrolysed with caustic alkali to give an aqueous solution of glycerin.

Title: Improvements relating to the mounting of tines or the like on agricultural implements
IPC: A01B35/26
Filed: 1938-04-05
Abstract: 513,423. Implements for working land. WALLACE & SONS, Ltd., J., and YOUNG, J. L. April 5, 1938, No. 10375. [Class 6 (i)] The tines of an agricultural implement are normally locked in their working position, the lock being constructed to give way when the tines meet an obstruction and the force required to re-set the lock being less than the force required to release it. Fig. 1 shows a part of an implement having two parallel rows of tines 1. The arm 4 of each tine is adjustably mounted by screws 9 in a slot in a holder 8 which is provided with a pivot pin 10 engaging slots 11 formed in the side walls 5 of a supporting bracket. Each bracket is secured to the tool bar 2 by bolts and nuts. The holders 8 are formed with recesses 12 which are engaged by spring-pressed plungers 13 projecting through apertures in the walls 5 of the brackets. The recesses 12 and plungers 13 are of wedge-shape and thus tend to resist any pivotal movement of the holders 8 about the pins 10. Sufficient obstruction to the tines will however cause the plungers to leave the recesses as the holders turn about the pivots 10. Each holder is made of tapering section to provide inclined planes 17 leading up to the edges of the recesses 12 as shown in Fig. 2. After the locking means 12, 13 has been released so that the holder 8 has swung about the pin 10 into an inoperative position as shown in Fig. 3, it is returned into the working position by sliding it to the ends of the slots 11 and then turning it upwardly till the plungers 13 engage the lower ends of the inclined planes 17. The holder is then slid back to its initial position and swung upwardly, the plungers riding up the inclined planes till they snap into the recesses 12. In a modification a number of tines are carried on a sub-frame which is displaced when the tines meet an obstruction, or the main tool bar carrying all the tines may be displaceable.
